Lung reduction system
First Claim
1. A method that uses a lung-volume-reduction device having a housing adapted to be secured to a chest of a patient, a conduit projecting from the housing, and a gas outlet positioned within the housing and in fluid communication with the conduit, wherein the method comprises:
- (a) inserting the conduit through an aperture in the chest wall of the patient into the lung of the patient, wherein the aperture passes from external to the patient through skin of the chest wall, through a parietal membrane and through a visceral membrane into the lung, and wherein the visceral membrane is sealed to the parietal membrane around the aperture to prevent pneumothorax; and
(b) securing the housing to the chest of the patient external to the patient so that air within the lung may vent to atmosphere external to the patient through the conduit via the housing.

Abstract
A lung-volume-reduction device for treating a lung to relieve symptoms of chronic obstructive pulmonary disease and/or emphysema. The device includes a chest-mounted housing and a conduit which projects from the housing through an aperture in the chest of the patient into the lung. The other end of the conduit is connected to flow-control device which may include a valve such as a one-way valve, check valve or pressure-actuated valve. The flow-control device is positioned within the chest-mounted housing. The lung-volume-reduction device permits gasses to pass through the conduit and flow-control device and vent to atmosphere external of the patient.

17. A method for treating chronic obstructive pulmonary disease comprising:
-
(a) receiving a device having an external component, the external component having a planar surface adapted to be secured to the chest of a patient, a conduit projecting from the planar surface of the external component, and a gas outlet positioned within the external component and in fluid communication with the conduit; (b) inserting the conduit through an aperture in the chest wall of the patient into the lung of the patient, wherein the aperture passes from external to the patient through skin of the chest wall, through a parietal membrane and through a visceral membrane into the lung, and wherein the visceral membrane is sealed to the parietal membrane around the aperture to prevent pneumothorax; and (c) securing the external component to the chest of the patient external to the patient so that air within the lung may vent to atmosphere external to the patient through the conduit via the external component. - View Dependent Claims (18, 19, 20)
